荷兰采购需求：隔热保温、温室遮阳网、温室保暖、温室保温毯、温室隔热材料、NFT水培

We are currently working on a business case for an NFT system project in Al-Kharj, Saudi Arabia, covering a cultivation area of around 5,000 m². Specifically, we need a pricing estimate for essential components, including gullies, support structures, and a drip irrigation system. Could you provide us with a rough price indication, either per square meter or as a total estimate? It would be helpful if you could outline any critical assumptions that factor into your pricing. A prompt response would be greatly appreciated to help us advance our project plans effectively. Thank you!
